A base class that lets plugin authors easily add additional BOMs to all apps. All the
dependencies in the BOM (and its transitives) will be added to the dependency
management lookup, so an app can use just the artifact id (e.g. "spring-jdbc") in a
@Grab. To install, implement the missing methods and list the class in
META-INF/services/org.springframework.boot.cli.compiler.SpringBootAstTransformation
. The Ordered.getOrder() value needs to be before
DependencyManagementBomTransformation.ORDER.
